Customized RF Components and Microwave


75 ohm band pass filters are widely used in broadcast industry to distribute audio or video content to audience. For more than two decades, Temwell is the one of the best suppliers of RF & Microwave solution. We have 26 years of experience in designing and producing helical band pass filters. To meet the needs of RF & Microwave, we use λ/4 wavelength technology to design 75 ohm helical band pass filters. The 75 ohm helical band pass filters can be used to isolate or filter out certain frequencies that lie within a particular band or range of frequencies.

Temwell supplies double tuning / triple tuning / quadruple tuning / quintuple tuning 75 ohm helical band pass filters. Center frequency range 42MHz-2600MHz with -3dB bandwidth 2MHz-120MHz, 3dB low insertion loss, high attenuation and minimum 12dB return loss. The 75 ohm helical band pass filters can support frequency fine-tuning. Click How to make self-tuning to learn tuning.
